Whether it is simply added to carbon black for strong conductivity, or after carbon black is mixed w

Xinxiang Delong Chemical recommends that you add pure conductive carbon black, because the conductive carbon black has a large specific surface area, high oil absorption value, and high structure, so the conductivity is very good, and mixing with carbon fiber will reduce the purity of the conductive carbon black.

Conductive carbon black properties.

The higher the oil absorption value, the higher the electrical conductivity.

The higher the structure, the higher the conductivity.

The larger the specific surface area, the better the conductivity.

The above summary hopes to help you.

Conductive carbon black is characterized by small particle size, particularly large specific surface area, and particularly good conductivity, which can play a role in liquid absorption and liquid retention in batteries. Carbon black conductive agents are: acetylene black, super P, super S, 350g, carbon fiber (VGCF), carbon nanotubes (CNTS), Kochen black (ketjenblackec300j, ketjenblackec600jd, carbon ecp, carbon ecp600jd).

acetylene black: acetylene black with a purity of more than 99% obtained by the decomposition and refining of by-product gas during calcium carbide or naphtha (crude gasoline) pyrolysis, and carbon black obtained after continuous pyrolysis; Super P: Small particle conductive carbon black, which can be used in both positive and negative electrodes, has no lithium storage function at all, and only plays a conductive role; Cochen Black:

Conductive carbon black is a carbon black with low or high resistance properties. It can give the product a conductive or anti-static effect. It is characterized by small particle size, large and rough specific surface area, high structure, and clean surface (few compounds).

It can be applied to different products, such as conductive rubber, conductive plastic, radio components, etc. The main varieties are acetylene, carbon black, etc., which are used in the battery industry.

Conductive carbon black is the main application.

1.Anti-static products: conductive foam tubes, charging rollers, static eliminators, anti-static conveyor belts, anti-static rubber sheets, anti-static boxes, hollow boards, anti-static tubes, medical rubber products, carpets, photocopier rollers, printing machine rollers, electronic component packaging films, explosion-proof cables; There are also antistatic mats, antistatic soles, etc.

2.Conductive products: cable shielding materials, surface heating elements, conductive films, elastic electrodes, printed circuits, conductive coatings, conductive inks, conductive fibers, conductive leather products and adhesives. Mining conveyor belts, mining plastic pipes, mining air ducts, etc.

Factors influencing the conductivity of carbon black.

1) The particle size of carbon black. In the case that it can be evenly dispersed, the smaller the particle size, the better the conductivity of the carbon black. However, small particle sizes make it difficult to disperse, which in turn affects electrical conductivity.

Therefore, it is necessary to control the particle size of carbon black within a certain range, and improve the conductivity under the condition that the number of carbon black particles per unit volume can be guaranteed and good dispersion can be ensured.

2) Carbon black structure. The oil absorption value of carbon black, that is, the size of DBP value, represents the structure of carbon black aggregates, generally speaking, when the DBP value is high, the carbon black has a chain branch structure and good conductivity.

3) Carbon black roughness. Because the conductivity of carbon black needs to have a certain roughness, the carbon black is easy to form conductive channels, and the difference between the nitrogen adsorption surface area of carbon black and the surface area of CTAB is large.

4) Surface volatiles. The volatiles on the surface of carbon black are mainly formed by some organic groups and oil films that are not completely cracked, forming a layer of marginal layer, which increases the potential barrier between carbon black particles, seriously affects the conductivity, and the volatiles must be controlled within a low limit.

5) Ash and moisture. The ash and moisture content in carbon black is high, which actually reduces the content of carbon black, and also has an adverse effect on conductivity, so it is necessary to pay attention to controlling the ash and moisture content in carbon black in production.

The domestic mainstream production of conductive carbon black manufacturers have Xinxiang Delong Chemical, imported from the Czech Republic, Cabot, Degusa, Orilong, etc., in comparison, the conductivity and stability of domestic conductive carbon black has gradually replaced the imported similar products, and the cost is low, the above answer hopes to help you, thank you for adopting!

Conductive carbon black refers to special carbon black with low resistance or high conductivity, which can give the product a conductive or anti-static effect.

Conductive carbon black can be divided into ordinary conductive carbon black, high conductive carbon black, superconductive carbon black, and special conductive carbon black according to its structure, specific surface area, and oil absorption value.

Carbon black is the same as carbon black. Carbon black itself is a semiconductor material, conductive carbon black has a low resistivity, can make rubber or plastic have a certain conductive performance, used in different conductive or antistatic products, such as antistatic or conductive rubber, plastic products, cable materials; It can also be used as a raw material for dry batteries.

According to its conductivity and manufacturing method, conductive carbon black can be divided into: conductive groove black (CC), conductive furnace carbon black (CF), superconducting furnace carbon black (SCF), special conductive furnace carbon black (XCF), etc. Acetylene carbon black (ACEF) is also a carbon black with good electrical conductivity.

First of all, please take a look at the conductive carbon black index:

The amount of superconducting carbon black added and the resistivity that can be achieved.

1.The amount of superconducting carbon black added in rubber products and the resistivity that can be achieved, the amount of superconducting carbon black added in rubber products is 10%, and its resistivity can reach 10 to the 6th power of cm, and if the addition amount is increased to 25-30%, the resistivity of rubber products can reach 25 ·cm.

2.The amount of superconducting carbon black added in plastic products and the resistivity that can be achieved, the amount of superconducting carbon black added in plastic products is 12%, and its resistivity can reach 10 to the 6-9th power ·cm, if the addition amount is increased to 25%, the resistivity of plastic products can reach 10 to the 3-5th power ·cm

For supercapacitors, the material is applied to nickel foam to prepare the working electrode, whether it is coated on one or both sides.

Graphite is used as the electrode material for the supercapacitor

First, because the graphite material Pajingzhao has good electrochemical stability and dust rentability, it can allow the supercapacitor to withstand higher cell voltage. The electrodes are not easily lost.

Second, it is because graphite materials are processed quickly and at low cost.

Third, because of the graphite material, it is light in weight and has good thermal and electrical conductivity. The electrode material used in supercapacitors is mainly carbon, but there are other types as well.

It is mainly used as a reinforcing agent and filler for rubber, and its consumption is about half of the rubber consumption, and the carbon black for rubber accounts for 94% of the total carbon black, of which about 60 is used in tire manufacturing. In addition, it is also used as a colorant for inks, coatings and plastics, as well as an ultraviolet shielding agent for plastic products. It is also an important additive in many other products, such as electrodes, dry batteries, resistors, explosives, cosmetics and polishing pastes.

Furnace black is mainly used in rubber products, the finer the particle size of carbon black, the better its reinforcing performance; The higher the structural degree of carbon black, the higher the tensile stress and modulus. Fine-grained reinforcing varieties are mainly used for tire treads to give tires excellent wear resistance. Other parts of the tire, such as the sidewall, ply layer, belt buffer layer and inner lining layer, require the rubber material to be resistant to flexure and cracking, resistant to ozone oxidation, with good resilience and low heat generation performance, and generally use a coarser particle size semi-reinforced type (specific surface area less than 40m2 g) furnace black.

Groove black for pigments is widely used in inks, coatings, and plastics. Inks, especially press inks, mainly use medium pigment groove black. In the paint manufacturing process, high-pigment tank black gives excellent blackness and gloss to high-grade automotive topcoats, and medium-pigment tank black is used in general industrial coatings.

In addition, medium pigment tank black is also commonly used as an ultraviolet shielding agent for polyolefins to improve the weather resistance of plastic products. Groove black for rubber is mainly used for tread rubber for tires, especially off-road and engineering tires, which gives the tread high strength and good wear resistance.

Hot crack black is mainly used in rubber products. Due to the coarse particle size and poor reinforcing performance, it is only used in occasions that require the maximum filling increment, such as in the manufacture of rubber pads, hoses, sponge products, sealing rings, tire linings, bead rubber and insulating products.

Carbon black is mainly used in the rubber industry, and tires are the main products. The carbon black used in the tire industry accounts for more than 80% of the carbon black required by the entire rubber industry. Generally, rubber products other than tires of various motor vehicles (including motorcycles) are collectively referred to as "rubber products".

The annual consumption of carbon black in rubber products accounts for about 20% of the carbon black used in rubber.

Carbon black is an important reinforcing filler in the reinforcing filling system, which has an important impact on the physical and mechanical properties and processing technology of rubber compounds, but its impact on the heat resistance, oil resistance, corrosion resistance and other properties of rubber compounds is far less direct than that of rubber, vulcanization system and protection system. Because of this, the general rubber formulators do not pay as much attention to the specific performance indicators of a certain carbon black as the carbon black technicians, and often only pay attention to the selection of a certain type of carbon black, without investigating the specific indicators of carbon black in detail, or through the combination of different varieties of carbon black, carbon black and inorganic fillers are used together to meet the requirements of the use of products. Therefore, it is difficult to quantify the impact of specific physical and chemical indicators of carbon black.

Carbon black is mainly used in various conductive rubber and anti-static rubber products, and is suitable for all kinds of conductive and antistatic silicone rubber, rubber and plastic, engineering plastics, cable materials, coatings, epoxy flooring, leather, ink, charging rollers, rubber rollers, foaming, sponges and other materials; It can also be used as a raw material for dry batteries and battery materials for new energy vehicles.
